Coding Classes in Hengelo | Modern Age Coders

Course picks for Hengelo

Four courses for the town of Stork and Signaal

A child in Woolde who wants to make sounds and games, a teenager in the Hasseler Es cleaning a messy dataset for a school project, a student in the Binnenstad building a first anomaly detector, and an adult in Groot Driene whose reports all start from someone else's filtered export. The opening lesson costs any of them nothing.

Ages 6 to 10

Scratch Coding for Kids

Projects with sound, where a child records a room, decides which noises to keep and which to cut, and hears why that depends on the game.

Hengelo today

From Stork in 1868 to a centre rebuilt after October 1944

Hengelo is a single woonplaats, which the statistics office divides into ten wijken and 62 buurten: the Binnenstad, the Hengelose Es, Noord, the Hasseler Es, Groot Driene, Wilderinkshoek, Woolde, Slangenbeek, the Berflo Es and the Buitengebied. The municipality has 6,084 hectares of land and 99 of water within 6,183, and a published density of 1,375 residents to the square kilometre.

The metaalstad

In 1868 C.T. Stork moved from Borne and set up a factory for machine parts in Hengelo, Gebr. Stork and Co. After it came other large works: Hazemeyer, Heemaf, the Koninklijke Nederlandse Zoutindustrie and Hollandse Signaalapparaten. Textiles were made here too at first, but over the century that industry concentrated more and more in Enschede, and Hengelo acquired the nickname metaalstad.

October 1944

As a junction of railway lines towards Germany, Hengelo was bombed during the war, and on 6 and 7 October 1944 the centre of the town was almost entirely destroyed. Later the characteristic white town hall also disappeared, to make way for a modern design with a tower.

Station and canal

Under the western part of the station platform runs the Europatunnel. On the Twentekanaal, the Hengelo lock forms part of the De Waarbeek lock complex.

Hollandse Signaalapparaten, from 1922

Hollandse Signaal Apparaten was founded in 1922 as NV Hazemeyers fabriek van signaalapparaten, a factory of signal apparatus. It was taken over from Philips in 1990, and the company, now part of the Thales group, makes advanced radar and infrared equipment and fire-control systems, among them the Active Phased Array Radar and SMART-L, according to the encyclopaedia entry for Thales Nederland.

Signal and clutter

The same echo, two opposite jobs

The table describes how radar works in general. It makes no claim about any particular product made in Hengelo; the encyclopaedia says only that the firm makes advanced radar.

One set of echoes, read for two different questions
Echo received	For a radar tracking aircraft	For a weather radar	What decides
Rain and hail	clutter, to be suppressed	the signal, to be measured	the question
An aircraft	the signal	a nuisance in the picture	the question
Waves on the sea	clutter for air tracking	of little interest	the question
Birds	false targets to reject	contamination to remove	both treat them as noise, for different reasons

The lesson is simple and easy to forget. Nothing in the echo itself says whether it is signal or noise; the label is added by whoever decides what the instrument is for. Data carries the same property. A spike in a sales series is an error to one analyst and the only interesting thing to another; background chatter in an audio file ruins a transcript and is exactly what a model detecting breaking glass must hear; duplicated orders are clutter for revenue and evidence for a study of how often customers re-order. Every filter that removes something is therefore a decision about a question, and it should be written down as one, because the next person to use the data may be asking something else.

Verified local facts

What the national figures say about Hengelo

Figures from the national statistics service as republished for the municipality, each with its year; then the encyclopaedia history; then the handful of sums made here.

Residents by age on 1 January 2026
Age group	Residents
Under 15	11,422
15 to 25	10,150
25 to 45	21,831
45 to 65	22,525
65 and over	18,117
Total	84,045

Over time

84,045 residents in 2026 against 77,409 in 1995, which the site gives as growth of 8.6 percent. In 2025 there were 42,352 men and 41,303 women.

Households

39,972 in 2025, averaging 2.05 people: 16,485 of one person, 11,278 of several people without children and 12,209 with children, which add up to the total.

Homes and incomes

40,426 dwellings in 2025, 23,043 bought and 17,383 rented; estimated average value 313,000 euro. Average income 32,600 euro per resident and 38,500 per income recipient in 2024, with 3 percent of residents in poverty.

Schools and students

26 primary establishments with 6,369 pupils, about 245 each, and 8 secondary establishments with 5,612, about 702 each. At institutions in the municipality the site counts 6,723 MBO, 2,260 higher professional and 860 university students.

Origin

In 2025, 71,699 residents were born in the Netherlands and 11,956 abroad; by origin, 61,095 were Dutch, 6,131 European and 16,429 from outside Europe. Both splits come to 83,655, the same as the men and women of that year.

The sums

84,045 minus 77,409 is 6,636. 6,369 over 26 is about 245 and 5,612 over 8 about 702. Every group table above was totalled only as a completeness check, and none of the encyclopaedia figures is combined with the statistics.

No part of this page is connected with Stork, Thales, the municipality of Hengelo or any school in Twente, and Modern Age Coders does not suggest otherwise. Population, homes, income and schools are the national statistics as published for Hengelo in the years shown. Stork, the other factories, the textile industry, the bombing of October 1944, the town hall, the Europatunnel and the De Waarbeek lock come from the encyclopaedia entry for Hengelo; the history of Hollandse Signaalapparaten comes from the entry for Thales Nederland. That entry gives 84,038 residents for 1 January 2026, a different source from the figure used here, and the two are not combined.

Signature project

Name the question before you clean the data

Most data pipelines begin with cleaning, and most cleaning removes things. The removal is only correct relative to a question, and the question is rarely written down.

1. State what the data is for

Before any filter, write one sentence: this dataset is being prepared to answer this question. The sentence decides what counts as noise, and without it no filter can be judged.

2. Keep what you remove

Send every removed row, sample or sound to a separate store instead of deleting it. Count it, look at it, and ask whether any of it would matter to a different question.

3. Label the filter by purpose

Name each cleaning step after the question it serves, for example removed for revenue reporting. The next user then knows the step belongs to someone else's question and can undo it.

Signal for one question, clutter for another
In the data	Removed as noise when asking	Essential when asking	What goes wrong if the filter is reused
Extreme values in transactions	what does a normal customer spend?	where is fraud happening?	the fraud model is trained without any fraud
Background sound in audio	what did the speaker say?	did glass break in the room?	the event detector never hears the event
Repeat orders from one customer	how much revenue came in?	how often do customers come back?	loyalty looks lower than it is
Annotators who disagree on a label	what is the correct label?	which examples are genuinely ambiguous?	the model is trained to be sure where nobody is
Rain echoes on a radar	where are the aircraft?	where is it raining?	the forecast has no rain in it

Why cleaned data is a decision, not a fact

A dataset that has been through a cleaning pipeline looks tidier and more trustworthy than the raw version, and it is usually handed on without its history. The next person sees rows and columns, not the rows that are missing or the reasons they went. In machine learning this matters twice over. Filters written to make a model train smoothly often remove exactly the rare, awkward cases a model will meet in real use, and the model then performs well on clean tests and badly in the world. Anomaly detection is the sharpest example: a system meant to find unusual events is sometimes trained on data from which unusual events were removed as noise. The defence is not to stop cleaning. It is to treat every filter as an answer to a named question, to keep what it removed, and to rebuild the cleaning when the question changes. Radar engineers have always understood this, because the same echo from the same cloud is clutter on one screen and the forecast on another.

Reliable pipeline

Five rules for filters that someone else will reuse

For cleaning scripts, audio processing, outlier rules, deduplication and labelling. Learned in the town that built signal apparatus for a century.

Cleaning with the question in view
Rule	In practice	The trap it avoids	The result
Purpose first	Write the question at the top of every cleaning script	Filters that nobody can judge	Cleaning that can be argued about
Quarantine, do not delete	Move removed records to a separate table with the reason	Evidence destroyed for good	A removed set you can study
Count every step	Log how many records each filter took out	A filter silently removing a third of the data	Visible cleaning
Keep the raw layer	Store untouched source data beside every cleaned version	No way back when the question changes	Cleaning that can be redone
Re-clean for new questions	Build a fresh cleaned set for each new purpose	One team's noise becoming another's blind spot	Data fit for the question asked

For younger learners

A game with a microphone, where the child decides which sounds should make the character jump and which to ignore. Then the rules change, and yesterday's ignored sound becomes the one that matters.

For teenagers

A messy dataset cleaned in Python twice, for two different questions. The teenager keeps what each cleaning removed and shows how the two answers would differ if the wrong cleaned set were used.

For adults

An export from a work system traced back to the filters applied before it arrived. Adults often find that the rows they most needed were removed long ago for somebody else's report.

This section rests on the encyclopaedia's account of Hollandse Signaalapparaten and on general knowledge of how radar and data cleaning work. It describes no specific system made in Hengelo and makes no claim about how any company there processes its data.

Learning ladder

From choosing which sounds to ignore to cleaning data for the right question

Nobody is placed by age or postcode alone. The free lesson shows the teacher how the learner tackles a real task, and the level follows from that.

Ages 6 to 10

Which sounds count

Children decide which noises a game should react to, and then the rules change.

Coding and AI

An AI will clean a dataset in seconds. Why should a teenager in Hengelo ask what the cleaning was for?

Because in the town of the signal-apparatus factory, the same echo can be clutter or the whole point.

Ask an AI assistant to tidy a dataset and it will remove outliers, drop duplicates and fill gaps in a few lines, following the conventions it has seen most often. Those conventions were written for common questions, usually about averages and totals. If the real question is about the rare case, the fraud, the fault or the unusual customer, the assistant has just deleted the answer, and the cleaned file gives no sign of it. Models trained on such cleaned data then learn a world with the interesting parts removed.

A learner who has cleaned one dataset twice for two different questions, and seen how differently the two versions answer, stops treating cleaning as housekeeping. Deciding what counts as noise, keeping what was removed and rebuilding the cleaning when the question changes are judgements about purpose. An assistant can carry them out once they are made. It cannot make them, because it does not know what the data is for.

So the reason for a child in Hengelo to learn to code in 2026 is not the town's engineering past. It is that someone who asks what the noise is noise for will be needed wherever AI tidies data before anybody has said what the data should answer. The longer argument is in why a child should still learn to code in 2026.

Delivery

Lessons for every wijk of Hengelo

From the Binnenstad to the Buitengebied, a Hengelo learner joins from home and the lesson is identical wherever the laptop happens to be.

Home is the classroom

Someone in Slangenbeek and someone in Noord open the same session at the same minute. There is no trip across town and nobody waiting outside a building afterwards.

Havo stays havo

The Dutch labels for school, from groep and brugklas through vmbo, havo and vwo to the profielkeuze, are used untranslated, while explanations are given in English.

Free, and a real lesson

The first session is taught properly on a genuine task rather than demonstrated. It closes with a recommended level, a course and a proposed weekly slot; no payment details are requested.

Matched classmates

Groups hold five to ten learners at one stage. Hengelo has 11,422 residents under fifteen, and finding five of them at an identical point, free at an identical hour, is unusual, so classmates can come from other countries.

Holidays of regio Noord

Sessions run twice a week, roughly eight times a month, at one fixed slot, and stop for the regio Noord school holidays that Overijssel follows.

Teachers on Indian time

The teaching team works in India, three and a half hours later than Dutch summer time and four and a half later in winter, which puts late afternoons, evenings and weekend mornings within easy reach.

Thirty-four schools in one town, and a group drawn wider

Hengelo has 26 primary establishments with 6,369 pupils and 8 secondary establishments with 5,612. A good coding group depends on a match of subject, stage and hour among five or more learners, and across every age from 6 to 67 and many countries that match is found far more readily than inside one town.

The first task might be deciding which sounds a game should hear, cleaning a small table while keeping what was removed, or preparing one dataset for two different questions.

FAQ

Hengelo coding class questions

The metaalstad, its factories, its figures, and how lessons run.

Which parts of Hengelo are there?

Hengelo is a single woonplaats. The statistics office divides it into ten wijken, the Binnenstad, the Hengelose Es, Noord, the Hasseler Es, Groot Driene, Wilderinkshoek, Woolde, Slangenbeek, the Berflo Es and the Buitengebied, with 62 buurten between them.

How many people live in Hengelo?

The national statistics count 84,045 residents on 1 January 2026, in 39,972 households in 2025. The count for 1995 was 77,409, and the figures site gives the growth since then as 8.6 percent.

Why is Hengelo called the metaalstad?

After C.T. Stork moved his machine-parts factory from Borne to Hengelo in 1868, other large works followed, among them Hazemeyer, Heemaf, the Koninklijke Nederlandse Zoutindustrie and Hollandse Signaalapparaten, and the town became known for metal and engineering rather than textiles.

What does Hollandse Signaalapparaten make?

Founded in 1922 as Hazemeyer's factory of signal apparatus and now part of the Thales group, it makes advanced radar and infrared equipment and fire-control systems, according to the encyclopaedia entry for Thales Nederland.

What happened to Hengelo in the war?

As a railway junction towards Germany the town was bombed, and on 6 and 7 October 1944 its centre was almost entirely destroyed. The characteristic white town hall later gave way to a modern design with a tower.

How many schools does Hengelo have?

The statistics count 26 primary establishments with 6,369 pupils and 8 secondary establishments with 5,612, plus 6,723 MBO, 2,260 higher professional and 860 university students at institutions in the municipality. No school is rated here.

Are lessons in English or Dutch, and when do they happen?

The teaching language is English, and Dutch school words like vmbo, havo and brugklas are left as they are. Teachers work on Indian time, three and a half hours ahead of the Netherlands in summer and four and a half in winter, so late-afternoon, evening and weekend slots are easy to arrange. The slot is fixed in the free lesson, and breaks follow the regio Noord holidays.

Is there a Modern Age Coders classroom in Hengelo?

No, and none is claimed here or anywhere in the Netherlands. All teaching is live and online and needs a laptop or desktop, working audio, a current browser and a connection that holds. The telephone number shown on this page is an Indian one and is described as such.

What do Hengelo coding classes cost?

The first lesson is free. After it, group tuition is USD 100 a month for two live lessons a week, normally eight across the month, in a group of five to ten learners. One-to-one tuition is USD 150 a month at the same frequency with a single teacher. Course, format, recurring hour and availability are all confirmed before anything is paid.

How many learners are in a group?

Five to ten, matched on level, pace and goal rather than on age, school or address. One-to-one means a single learner with a single teacher. When no group at the right level is running, a family can take one-to-one lessons or wait for the next group to form.
